Since its creation in 1998, the Implicit Association Test (IAT) has become a commonly used measure in social psychology and related fields of research. Studies of the cognitive processes involved in the IAT are necessary to establish the validity of this measure and to suggest further refinements to its use and interpretation. The current thesis used ERPs to study cognitive processes associated with the IAT. The first experiment found significant differences in P300 amplitude in the Congruent and Incongruent conditions, which were interpreted as a reflection of greater equivocation in the Incongruent condition. The second experiment tested the task-set switching account of the IAT in much greater detail by analyzing each trial type separately. In the Congruent condition, all trial types elicited the same amplitude P300. Local probability, and the consequent checking and updating of working memory, was thought to be responsible for differences between trials of the Incongruent condition that required or did not require a task switch. The final experiment examined the role of working memory in the IAT by introducing obtrusive and irrelevant auditory stimuli. The results of Experiment 3 indicated that the introduction of an obtrusive and irrelevant auditory increment deviant has little overall effect on the IAT, and a similar effect on switch and no-switch trials within the Incongruent condition. This could have been because both the Congruent and Incongruent conditions of the IAT make such extensive demands on central processing resources that few are available to allow for the switching of attention, or it is possible that the IAT does not require significant updating of working memory. The usefulness of ERPs in the study of the IAT effect is demonstrated by the current research. In particular, the finding that behavioural results were not always consistent with the ERP results demonstrates that electrophysiological measures can complement traditional behavioural measures.

Many cognitive resources contribute towards the appraisal of stressors. Of these, self-efficacy (SE) is widely acknowledged to play a significant role in protecting adolescents from the effects of stress (Bandura, 1997). This study investigated that relationship through the use of a quasi-experimental methodology (Cook & Campbell, 1979) utilising an untreated Control group of 44 adolescent, female participants and an Experimental group of 70 additional participants, all of whom were volunteers drawn from the Sixth Form of a single participating school. The members of both participant groups took part in two rounds of testing, between which the members of the Experimental group were exposed to a significant academic stressor (one or more public A-level examinations). During both test phases, all participants completed the 10- item Perceived Stress Scale self-report (Cohen & Williamson, 1988), the Examination Self-Efficacy Scale instrument (Schwarzer & Jerusalem, 1995) and a bespoke Implicit Association Test (Greenwald et al., 1998) designed to measure implicit stressor appraisal. Significant trends were identified by means of ANCOVA, correlation and regression analyses, and the resulting data were interpreted in terms of a dual process model of stress (Compas, 2004). Results not only concurred with those of previous studies (e.g. Betoret, 2006; Vaezi & Fallah, 2011) by demonstrating a strongly negative correlation between acute academic stress and academic SE, but provided new evidence to suggest that the ‘protective’ effect of SE occurs via a buffering mechanism at the level of preconscious stressor appraisals (Bargh, 1990), which limits the effect of acute stress exposure on preconscious stressor appraisals (e.g. Luecken & Appelhans, 2005).

Thesis advisor: Andrea Heberlein / Dehumanization of outgroup members in situations of intergroup competition has been widely reported (Haslam, 2006), but the effects of individual competition on dehumanization have not yet been extensively explored. A previous study in our lab examined this effect and found an unexpected gender difference, with women showing greater implicit dehumanization than men. The present study aimed to explore a possible mechanism for that gender difference: gendered expectations of maintaining positive interpersonal relations, and subsequent discomfort in competitive situations, may motivate the implicit dehumanization of competitors. Participants interacted briefly with a confederate and were then given instructions for a competitive or non-competitive game. Participants then completed two Single-Category Implicit Association Tests measuring dehumanization of their game partner. Participants also completed the Mind Perception Questionnaire, which measures explicit dehumanization of participants’ game partners. We predicted that in the Competition condition, female participants would implicitly dehumanize their game partners more than men would. / Thesis (BA) — Boston College, 2018. / Submitted to: Boston College.

In a series of two experiments, the first involving 121 participants and the second 114, I investigated whether level of racial prejudice is related to performance on a cognitive task and helping behavior in participants who had just interacted with the target of their prejudice. The moderating effect of control was tested and, unlike previous research, the responses of African-American participants were studied too. It was proposed that when people interact with the target of their prejudice, they will experience stress and the aftereffects of stress will lead to a decrement in Stroop task performance and a lower likelihood of helping someone in need. Control was believed to moderate this effect such that those given control would suffer less of a performance decrement and would help more often. Data were analyzed using ANCOVA and logistic regression. Racial prejudice was found to affect European-American but not African-American Stroop performance following the interracial interaction. Control moderated this effect and also influenced whether someone helped a person in need.

Tidigare forskning har visat att implicita och explicita attityder formas och förändras oberoende av varandra, samt att allt fler politiker använder sig av sociala medier för att nå ut till sina väljare. Denna studie syftade till att undersöka hur deltagarnas implicita och explicita attityder, gentemot två fiktiva politiker, påverkas av traditionella och sociala medier. I studien användes en experimentell mellangruppsdesign där deltagarna slumpmässigt fördelades till olika betingelser. Dessa bestod av positiva och negativa nyhetsitems från dels traditionella dels sociala medier. I undersökningen, som genomfördes på internet, deltog 126 personer. För att mäta deltagarnas attitydförändringar användes dels ett Implicit Association Test (IAT), dels ett explicit frågeformulär. Traditionella media påverkade explicita attityder signifikant.

Implicit prejudice, and in particular, the Implicit Association Test (IAT), are paradigmatic examples of psychological concepts and research methods that have recently enjoyed great publicity and accessibility. However, little is known about the possible reflexive consequences of this popularization for the public understanding of prejudice, and by implication, for the formulation of social policy aimed at the reduction of prejudice and racism. Specifically, how does the public interpret and contextualize the claims of the IAT and implicit prejudice? With what social and political preoccupations does this operationalization of implicit prejudice resonate? Furthermore, how do members of the public experience and interpret the IAT as both a scientific instrument and as a bearer of psychological truth? In answer to these questions, this dissertation comprises a report of two empirical studies of public encounters with the IAT and the concepts of implicit prejudice. The first of these focused on popular responses to IAT research in the New York Times. Employing a discourse analytic approach to reader comments, it identified the social and psychological concerns against which the public makes sense of the IAT. In responding to the IAT, readers drew on skeptical and confessional discourses to position themselves reflexively in relation to its claims. I argue that these discourses constitute a space within which strong injunctions to self-scrutiny, impartiality and objectivity are established as moral-psychological ideals. Building on these findings, the second study examined the IAT as a discursive practice through a focus on the lived experience of taking the test. Recruited participants took the IAT, and were subsequently interviewed to elicit moment-by-moment accounts of this process. Hermeneutic-phenomenological analysis of these accounts revealed thematic concerns that both resonated with and augmented those in the analysis of public discourse. In particular, the IAT was experienced as a vivid demonstration of the operationalization of "implicit bias". I argue that the test embodies and communicates this paradigm to test-takers, and therefore functions as a psychological pedagogical tool. The dissertation closes by discussing the implications of these analyses for public understandings of, and responses to, prejudice.
